1 invention relates-to the folding bed art being more particularly a folding bedmounted on a carriage, such carriage bein'gmou'nt: W

ed on Wheels whereby the bed maybe moved about a room or intoa closet as desired. 4 f In bed construction of the-class referred to, the. carriage is usually of small size so that when thebed is in foldedposition the entire Organization may freely pass througha door 0 opening, consequently duringthe operation of opening the bed there is a liability that the .bed together with the carriage will tipfover. It isone of the principal objects oiimyim ention to produce a bedgof the character described of simple form and operation inwhich Fig. 1 is a'plan'view of abed structure enfbodylngva form of myinvntion showing the bed inv up ended or closed-position.

At each sideof the frame; 12 is'a' standard permit 17 and an associated brace-member" 18,1 the 1 upper end of such'standard and brace mam- 5 ber belng slotted as shown at19to receivea" pivotpin orbplt 20 on the side rails 21*of;t he bed framejgenerally ihdibated iitlQQ-f The "wheels l5 afiord ample flsup'portgfor the en tire structure when theIbe'dYiS"illifolded'or nn closed position but'during lowerin move- 'ment of theflbed braeingjineans are provided which consist of outwardly movable arn 25 provided with rollers 26 attheirouterfends, which rollers are out of engagement with'the ts floor as shown in Fig; 3jexcept when thebe'd is in the actjof being lowered, dnri'ngwhich time thejrollers engage the floor." i

1 Each arm 25Tis pivotallyr mounted channel member 27 of the carriage 11 by F20 means ofa headed bolt'27 which extends through f a boss -28 being secured; thereto by means of 'a' pin 29, theup'pe'rfend ofjthe bolt 27 having secured thereto, bym'eans of apin moved outwardly operating the;link'32, and s5 leyer '31 to swingthefarm's25. into retracted position. 'f

The block 33 carries a st-riking plate lt, which is engaged by the cross bar'AQ of the bed when the bed is lowered,ithisfaction cans be ing an outward movement ofthe arms 25 into operative position. The striking plate 445, is pivotally mounted onthe block-'33 byfQmeans f i the other nd ofthe lat 44 be'n I .,Describing more particularly the'embodi- 0 e p e 1 fixed in adjusted position; onithe block by meansof a bolt 4 6 which .extends'through' a slot 47 indicated in dotted lines in Fig;;-.6, which'bolt 46 alsopivotally supports alocking member in the form of a finger 48 h'aving i a pin 49 thereon 'at one end whiche'r'lgages a are perforation 50 in the channel 26 to hold the block 33 against movement when the arms 25 are in extended position, the cross bar 42 engaging the finger 48 to release the pin 49 from the channel 26 just prior to engagement ofthe crossbar 42 With the abutment or lug 41 on the block33. a

When in extended position the senses are slightly depressed to bring the rollers 26'into engagement with the floor indicated atsffl. This is accomplished by means of a depending rod 53 mounted on a bell crank lever 54 which lowered this leg 60 'sw'i s Outward pin in the slots tliejjupper s an rd ,17" and brace 184' M 3 li is pivotally mounted on a plate' 55 secured to the carriage 11.
